SGD-SB2025NT-TUM, Part 1 1 INTRODUCTION The SB2025 Series of Base Stations are based on the SB2000 base station with integrated Solar 2 hardware to give additional functionality. They employ state of the art design and construction methods to deliver a range of high performance, ultra reliable radio transceivers.
SGD-SB2025NT-TUM, Part 1 A radio system will necessitate the use of a number of Solar NIs and one or more Solar TMs, which together are configured to meet the operational requirement. The Solar NI operates as a Central NI or a Station NI; they are the same unit. They are fully duplex and include all the features; it is a matter of system configuration to define which is which and how they are used.
SGD-SB2025NT-TUM, Part 1 • Return (RTN) path – Talk In direction. The synchronization process requires access to a globally available 1PPS (Global Positioning System (GPS)); when configured as ‘enabled’ the process is automatic; there is no manual version, although the average value of delays being experienced across the network will be displayed on the Engineering Terminal (ET). (b). Multicast style Solar will operate in systems that are built as Multicast, i.e.
SGD-SB2025NT-TUM, Part 1 In the Tx direction (outgoing), the TM constructs the P25 frames from the voice data bit stream coming from the Central NI or DFSI in IP packets or from the voted Station NI if in Talkthrough (T/T) mode. The TM sends out the P25 frames in IP packets to every Station NI on the channel. In non-P25 mode, the packets from the Central NI or voted Station NI are basically replicated for each Station NI.
SGD-SB2025NT-TUM, Part 1 2 SPECIFICATIONS 2.1 GENERAL SPECIFICATIONS Table 1. General Specifications.

SGD-SB2025NT-TUM, Part 1 3.2.3 Adjustments There are two categories of adjustable parameters in the SB2025: • those that are controlled by conventional potentiometers, which may be manually adjusted; and • those controlled by digital potentiometers, which are under the control of the Micro Controller. The latter category of items comprises Tx power, Tx Voltage Controlled Oscillator (VCO) deviation, Tx reference oscillator deviation and Tx reference oscillator frequency.
SGD-SB2025NT-TUM, Part 1 4 GENERAL DESCRIPTION The SB2025 series employs state of the art design and construction methods to deliver a range of high performance, ultra reliable radio transceivers. They are ideally suited for use in VHF or UHF two way voice radio systems, however, the SB2025 can perform in a range of applications where the added advantage of linear frequency and phase response from DC to 3.4 kHz can be utilised.

SGD-SB2025NT-TUM, Part 1 4.2 ENVIRONMENT I/O OVERVIEW The Environment I/O interface module in Solar provides a facility to monitor and control external devices in a simple “ON/OFF” or “Active/Inactive” state. This information is conveyed via the data packet protocol such that a change in input status and output change command will be notified, typically within 1 second.
SGD-SB2025NT-TUM, Part 1 The environment I/O is arranged into two groups where each group connects to the same physical device (integrated circuit). To keep the power dissipation of each device within operating limits, the total current that may be switched by all the control outputs in one group must not exceed 500 mA when all outputs are “ON”. 4.3 4.3.
SGD-SB2025NT-TUM, Part 1 The Press (Push) To Talk (PTT) signal enables the amplifier circuit by providing bias to the transistors. A thermistor TS1, physically located on the PA heatsink monitors the heatsink’s temperature and is monitored by the Micro Controller. The PA is very compact and efficient for high reliability and low cost. The heatsink has minimal temperature rise even under continuous operation, ensuring the best Mean Time Between Failure (MTBF) obtainable for a practical design. 4.3.
SGD-SB2025NT-TUM, Part 1 4.3.8 SBC Support PCB This PCB includes a 5-port Ethernet switch, two USB sockets, physical support for the Pico Power Supply Unit (PSU), USB Universal Asynchronous Receiver/Transmitter (UART) and RS232 interfaces for the ITX. 4.3.9 Aux PCB This PCB contains a micro controller that monitors the operation of the ITX and will attempt to reboot it if necessary.
SGD-SB2025NT-TUM, Part 1 5 TECHNICAL DESCRIPTION The internal design of the SB2025NT is of a modular nature allowing for simple configuration and maintenance while ensuring minimal downtime. For reference purposes, the block diagram of the SB2025NT is shown in Figure 4. 5.1 EXCITER MODULE RF from the VCO on SKU-1 at a nominal level of +3 dBm is applied to the fractional-N synthesiser IC10 main divider input.
SGD-SB2025NT-TUM, Part 1 the Micro Controller board on SKD-3. The RSSI from IC1 is buffered by IC5A and connected to the Micro Controller board via SKD-4. RF from the VCO on SKU-1 at a nominal level of +3 dBm is applied to the fractional-N synthesiser (IC10) main divider input. This signal is compared with the reference oscillator frequency and the correction voltage from the synthesiser’s charge pump output is filtered then amplified by the noninverting low noise operational amplifier (IC11A).

SGD-SB2025NT-TUM, Part 1 The Micro Controller sends programming data to the synthesiser ICs on the Rx and Exciter modules each time the channel is changed as well as on PTT. This information is communicated to the Rx and Exciter modules by way of bussed data and clock lines on SKC/D-18 and SKC/D-15 (Exciter/Rx) and an individual module strobe on SKC/D-17. A lock detect signal from each module on SKC/D-16 is read by the Micro Controller.
SGD-SB2025NT-TUM, Part 1 between Rx audio and Tx looped back audio for output to line via amplifiers IC40A and IC40B. Secondary inputs to these amplifiers are the Tx audio from the line modem and microphone audio to line. The output on SKH-2 forms an unbalanced 600 Ω VF output to line and, alternatively, outputs SKH-2 and SKH-11 form a differential output.
SGD-SB2025NT-TUM, Part 1 This application receives packets from one or more NIs every 20 ms, votes the best quality signal and presents it to a dispatcher either via a DFSI connection or as an analogue 4-wire using an additional stand-alone Network Interface. Outgoing analogue or P25 audio/data from analogue dispatcher, DFSI or voted call is timestamped and sent to all associated NIs for transmission. If multiple NIs are connected they can be synchronised to create a simulcast channel.

SGD-SB2025NT-TUM, Part 1 7. Adjust the mute level potentiometer, RV6, until the mute opens then wind it back until it just closes. New Motherboards (PCB Rev >R), have a new software digital controlled mute function. This provides the user with the ability to program the SB2025NT with three different mute settings. These setting can be changed on the fly by a PC when connected via RS232. These controls are located within MxTools Configuration screen, under Mute/Squelch settings tab.
SGD-SB2025NT-TUM, Part 1 6.2 MODULE LEVEL TEST PROCEDURES The following alignment and testing procedures are based upon using a working transceiver as the test environment. It is also assumed that test fixtures to the radio are available to exercise control lines and monitor outputs and that a PC with MxTools is connected to the radio. There are four modules in the SB2025 – the Exciter, Rx, PA and Micro Controller. The Exciter and the Rx have VCO daughter boards. The Rx and Exciter VCOs are similar. 6.
SGD-SB2025NT-TUM, Part 1 12. On the MxTools Channel Edit screen, adjust the ‘Tx RF Power’ digital potentiometer slider to 0 (zero) and check that the power control volts on SKD-4 drops to 0 V and that the RF power out drops to <1 mW. 13.

The ‘Continuous Update Enabled’ option on the MxTools Channel Edit screen should be selected for these tests. 2. Remove the top cover from Exciter module and fit the VCO under test. As the Tx and Rx VCOs are identical, the Rx VCO may also be tested in an Exciter.
SGD-SB2025NT-TUM, Part 1 7 FAULT FINDING PROCEDURES The following test equipment may be required for the tests detailed in this section: • PC with MxTools (SB2025 Base Station Programming Utility). • RF Test Set (e.g. HP 8920 or equivalent). • Oscilloscope. • RF Power Meter (capable of measuring to 60 Watts continuously). • Multimeter. • +13.8 V DC Power Supply (capable of supplying 15 Amps). • Network Analyser. • SB2025 Test Jig (Optional). 7.
SGD-SB2025NT-TUM, Part 1 7. If the Diagnostics shows abnormal, on the Motherboard, check the voltage on pin 62 of IC1. If the voltage is low (i.e. <200 mV), the likely fault is IC1. If the voltage is >200 mV, the likely fault is within the PA module. 8. If the Diagnostics shows normal, check the RF level from the Exciter module by connecting a Power Meter directly to the Exciter RF connector. In MxTools, adjust the ‘Transmit Power’ control to maximum, the RF level should be >+23 dBm (200 mW).
SGD-SB2025NT-TUM, Part 1 3. The Micro Controller PCB requires specialised test software to check all the hardware input and output ports. Please contact Simoco Customer Services and arrange for the Micro Controller PCB to be returned to Simoco’s Service Centre. 7.3 RECEIVER MODULE 7.3.1 VCO Locking. 1. In MxTools, check that all hardware settings are correct. 2. On the Rx Module, check the value of X3 (13 MHz or 14.
SGD-SB2025NT-TUM, Part 1 7. Adjust T1 and T2 for minimum distortion <1%. 8. If the distortion is high, FL3A, FL3B or FL4 may be faulty. 9. If the sensitivity is still poor, contact Simoco Customer Services and arrange for the Module to be returned to Simoco’s Service Centre. 7.4 EXCITER MODULE 7.4.1 VCO Locking 1. On the Exciter module, check the reference frequency of X3 (13 MHz or 14.4 MHz) is the same as the Tx Reference Frequency in the ‘Hardware Settings’ on the MxTools configuration menu.
SGD-SB2025NT-TUM, Part 1 4. With PTT ON, measure the PA bias current at the gates of the FETs. The bias current is band dependent. This is done by monitoring the current drain of the whole PA with CN1 disconnected. Link the gate of TR2 to GND. Measure current consumption (VHF High Band 200 mA, VHF low and UHF 400 mA). This can be adjusted by RV2. Measure gate volts ≈ 3.4 V. 5. Remove the link from TR2.

SGD-SB2025NT-TUM, Part 2 1 INTRODUCTION TO THE ENGINEERING TERMINAL 1.1 ENGINEERING TERMINAL OVERVIEW In the context of engineering, the ET is the primary source for control and monitoring of a Solar Network for both Analogue and P25 systems. It must be stressed that the ET is not designed for use by a control operator; a bespoke supervisory application or Simple Network Management Protocol (SNMP) is best suited for that task. Basic connection of the ET is to the front panel USB (Type B) connector.
SGD-SB2025NT-TUM, Part 2 Figure 1. ET window – Status Bar. 1.3.1 Default Setting If this is the first usage of an ET application, there will be no default settings, otherwise the settings will be those used on the last occasion taking information held in an “ini” configuration file. If this file is not found, it will be automatically created in the same folder as that holding the application itself.
SGD-SB2025NT-TUM, Part 2 2. On the ET Setup window (see Figure 4 below), in the ‘Communications Parameters’ area, carry out the following: 2.1. Using the drop-down list, select the ‘Direct’ Method. 2.2. Using the drop-down list, select the COM Port required. Note. Only valid com port numbers will be available. 2.3. Select ‘Close’. 3. On the ET window, from the menu bar, select Options > Connect to return to the original opening view. Figure 4. ET Setup window. 1.3.
SGD-SB2025NT-TUM, Part 2 Figure 5. Connected sub-window. On selecting the ‘Disconnect’ button, the application will terminate the data exchange with the equipment, the PC Com Port will be released and the window view will return to that which was seen when the ET was first run showing the ‘Disconnected’ sub-window (see Figure 6). Figure 6. Disconnected sub-window. 1.4.
SGD-SB2025NT-TUM, Part 2 1.5.2 Releasing the Engineering Button It should be noted that failing to release the ‘Eng’ button on either the NI or the TM ET will result in any incomplete changes (those not applied) being held in the ET memory, therefore, subsequently applying another change even on a different page will automatically invoke incomplete changes as well. This is also true if a “new” NI has now got the focus of the ET.
SGD-SB2025NT-TUM, Part 2 Figure 7. Button options.
SGD-SB2025NT-TUM, Part 2 2 NETWORK INTERFACE ET The screen displays for the NI in this section are those that will be seen when directly connected to the NI using the front panel USB connection. When accessing an NI remotely through the TM, the view remains largely the same but only a single ‘Eng’ function is available (see Section 3.5 – Remote View of an NI). 2.1 INTRODUCTION The initial main window view of an unconfigured and unconnected NI is shown below in Figure 8. Figure 8. An Unconfigured NI.
SGD-SB2025NT-TUM, Part 2 Figure 9(a). Central Mode. Figure 9(b). Station Mode. The following sections will outline the meaning of the indications on the NI ET main window. The purpose of the buttons will be described here but their full usage is covered under other sections. 2.2 NI MODE PANEL All indications shown in the figures overleaf are shown in an inactive state. A Central NI is shown in Figure 10a and a Station NI is shown in Figure 10b.
SGD-SB2025NT-TUM, Part 2 Rx = Receiver active: Yellow = Active; Red flashing = Inhibited. Tx = Transmitter PTT: Yellow = Active; Red flashing = Inhibited. Control/Console operator initiated transmit function. Control/Console operator initiated T/T (repeat) function. Incoming (receiving) call present. RSSI level: Yellow rising bar for normal RSSI; Blue full height bar = “Eng Call” RSSI Value: 0 = no signal; 14 = top RSSI; 15 = “ Eng Call” Warning indications of engineering test facilities in use.
SGD-SB2025NT-TUM, Part 2 2.3.1 Address This indicates the role of the NI in the context of the Solar network. It is not manually entered as it is derived automatically when the NI is allocated to a role by the TM during the TM configuration process. The prefix ‘CEN’ indicates that the mode is “Central” and the prefix ‘STN’ indicates the mode is “Station”. The suffix indicates the operating number that this unit has been assigned; for Central the number is in the range of 1 to 16, for Stations 1 to 32.
SGD-SB2025NT-TUM, Part 2 Moving the mouse pointer over the ‘In’ indicator will show information about packet errors – see Section 2.4.1.4 below. A network failure may be assigned to ‘Alarm’ status – see Section 12 – Alarms. There will be a delay of several seconds between the moment of network failure and the failed indication appearing, in order to prevent short drop-outs from raising the alarm. 2.4.1.
SGD-SB2025NT-TUM, Part 2 Losing the 1PPS timing signal will cause the frequency and phase error reports to show zero. On resumption of the timing signal and, depending upon the period of time that the timing signal was lost, a ‘Freq Error’ may be seen, however, a ‘Phase Error’ is the most likely result together with the ‘Status’ indication being lit Red. Errors will be corrected as described above.
SGD-SB2025NT-TUM, Part 2 Figure 13. Environment I/O. 2.5.2 Indicators Each connection point is able to operate as an input or an output, which is defined by the configuration mode for each connection (see Section 5.2.4 – Environment). Inputs are denoted by a circular indicator and outputs by a square indicator. An active input or output is shown by the corresponding indicator being lit Yellow as seen in Figure 13 above.
SGD-SB2025NT-TUM, Part 2 As the TM also needs a timing signal, the identical facility is available to the TM ET (although not for a remote view of the NI). Therefore, details of the GPS window and the indicators for both ETs are given in Section 9.1 – GPS.
SGD-SB2025NT-TUM, Part 2 3 TRAFFIC MANAGER ET 3.1 INTRODUCTION The main operating entry level window to the Solar TM ET application software is shown below in Figure 15. It provides a reflection of the Solar network status. The Station NI panels will be blank until assigned an IP address of the respective NI and enabled whereupon additional indicators and a control become visible. 3.
SGD-SB2025NT-TUM, Part 2 3.3 UPPER AREA 3.3.1 Station NI Panels As a minimum, each panel in the upper area of the TM ET will have a numbered button displayed. This button is the route to the IP address assignment facility as shown in Section 4.4.3 – Allocating a Station NI. A second button, a bar and a round coloured indicator will appear once the panel has been allocated to an NI, i.e. given the IP address of an NI and “Enabled” (see Figure 16 below).
SGD-SB2025NT-TUM, Part 2 3.4 LOWER AREA 3.4.1 TM Status Panel The TM Status panel is selected by selecting the ‘TM’ tab (indicated in Figure 17 below). The example shown below in Figure 17 is of a TM with the maximum number of channels enabled; a typical TM configuration is likely to have many fewer channels. When used with a Solar 2 P25 system, a maximum of four channels can be enabled (see Figure 18). Figure 17. TM Status Panel. Figure 18. TM Status Panel for P25 system.
SGD-SB2025NT-TUM, Part 2 3.4.1.3 Facility Key A normal operating state is indicated by the status indicator being lit Green, an abnormal state by a status indicator being lit Red. See Section 9.2 – Facility Key for full details. 3.4.1.4 Network See Section 4.3 – Setting the TM IP Address for full details. 3.4.1.5 Eng See Section 5.3 – TM Engineering for full details. 3.4.1.6 GPS See Section 9.1 – GPS for full details. 3.4.1.
SGD-SB2025NT-TUM, Part 2 3.4.2.1 Name A simple text label that can be entered by the user through ‘Setup’ to identify one channel from another (see Section 5.4.1 – Name). 3.4.2.2 Status (a). ‘MTx Key’ – lit Yellow when the channel is keyed either by a control PTT from a Central NI or as a result of a voted signal being present while T/T is on. (b). ‘Talk Thru’ – lit Yellow when the channel has T/T switched on either by an input signal to a Central NI or a setting of the TM Setup. (c).
SGD-SB2025NT-TUM, Part 2 3.5 REMOTE VIEW OF A NI The facility to remotely examine the status and adjust the engineering settings of a NI from a connection to the TM is enormously beneficial especially if the host network permits this to be achieved from anywhere on the network. The view of any NI when accessed in this way is essentially the same as for a local NI ET connection, the main difference being the number and designation of the buttons across the lower area.
SGD-SB2025NT-TUM, Part 2 4 SOLAR CONFIGURATION 4.1 IP ADDRESSES For efficient and effective user interaction with the ET, it is essential that the user has knowledge of the topography of the system. Before anything else can happen the IP addresses of the equipment must be assigned and set. The assigned IP address for an individual unit on any monolithic network must be unique, i.e. there must not be more than one equipment unit with a given IP address.
SGD-SB2025NT-TUM, Part 2 2.1. Enter the IP address and subnet mask. Note. The subnet mask and gateway address are not required by a NI but this facility has been provided for possible future upgrades. 2.2. Check the ‘Enable’ box. 2.3. Select ‘Apply’ and then ‘Close’. 3. Repeat Paras 1 to 2.3 above for every NI in the system. It may prove helpful if the IP address is noted on the NI case to save having to reconnect the NI ET later just to find that detail (it is not visible to the TM ET). 4.
SGD-SB2025NT-TUM, Part 2 3.2. From the drop-down list, set the ‘Traffic Manager Duplication’ option to ‘Unduplicated’. (If the duplication option has not been purchased then ‘Unduplicated’ will be the only available item in the drop-down list). Note. Even if the final system configuration is to use the ‘Traffic Manager Duplication’ option, at this stage it should be set as “Unduplicated”. This option can be changed later as detailed in Section 8 – TM Duplication. 3.3. Select ‘Apply’ then ‘Close’. 4.3.
SGD-SB2025NT-TUM, Part 2 Configuration can now continue as for a local connection. However, it will not be possible to change any of the IP parameters of the TM itself whilst connected in this way but this information will be displayed when the TM ‘Network’ button is clicked. 4.4 TM ADDRESS INVENTORY The next stage is to inform the TM of all the NIs that will operate within the Solar network.
SGD-SB2025NT-TUM, Part 2 Figure 25. Allocating a Station NI. The allocation process is as follows: 1. On the TM ET window, on the relevant station panel, click the “identity” button to gain access to the ‘NI Setup’ page. 2. On the ‘NI Setup’ page, carry out the following: 2.1. Enter the ‘IP address’ of the NI that is to be used as the Station Interface for that number. 2.2. Check the ‘Enable’ check box. 2.3. Select ‘Apply’ > ‘Close’. 3. Repeat Paras 1 to 2.3 for each Station NI on the system.
SGD-SB2025NT-TUM, Part 2 Note. If an IP address is entered that is the same as one already actively in use anywhere on the TM this will be cleared back to the previous setting when ‘Apply’ is clicked. 4.4.4 Allocating a Central NI The process and rules for the allocation of a NI as a Central unit are much the same as for a Station. Figure 27. Allocating a Central NI. The allocation process is as follows: 1.
SGD-SB2025NT-TUM, Part 2 Figure 28. Central #1 allocated and operating. 4.4.5 Channel Designation (Multi-channel TM Option) At this stage, every Station NI will be assigned to operate on Channel 1 – this is the default setting. This does not affect the commissioning process, although it is likely that the task will be conducted on a channel by channel basis.
SGD-SB2025NT-TUM, Part 2 5 SOLAR COMMISSIONING 5.1 COMMISSIONING OVERVIEW Solar commissioning falls into two stages: (a). Configuring the analogue interface of each NI to suit the requirements of the connected equipment. (b). Configuring the system parameters to meet the operational requirements. Stages (a) lies entirely with the NI and comes under ‘Engineering’ settings, which can be set using the TM ET as well as the NI ET.
SGD-SB2025NT-TUM, Part 2 Figure 29. NI Engineering – Main Audio (Analogue). The ‘Main Audio’ page of the NI Engineering facility for a P25 system is shown below in Figure 30. Figure 30. NI Engineering – Main Audio (P25). 5.2.1.1 In Audio Sensitivity The input sensitivity is determined by adjustment of a coarse gain setting (left slider) and a fine gain setting (right slider) (see Figure 31). The gauge on the right is an expanded view of the left hand gauge to provide greater accuracy of setting.
SGD-SB2025NT-TUM, Part 2 When a level change is applied, the marker alongside the slider will turn Blue until the change is confirmed, whereupon the position of the marker will match that of the slider control pointer and turn Grey again. Sliders Markers Figure 31. Audio I/P Level adjustment. 5.2.1.2 Audio Input Setup Process The following process is used to setup the audio input sensitivity: 1. Apply a test tone (see note) to the input at the required Peak System Level (PSL). Note.
SGD-SB2025NT-TUM, Part 2 5.2.1.3 Out Audio Level The audio output level is set using a coarse level control (left slider) and fine level control (right slider) (see Figure 32). The current settings are shown by the marker to the right of the slider and the value at the bottom. Figure 32. Audio Output Level adjustment.
SGD-SB2025NT-TUM, Part 2 Note. A change in the coarse gain setting will cause the PLL to show an error and possibly an alarm for a short duration. 5.2.1.5 In Route The ‘In Route’ functions available for an Analogue system are shown below in Figure 33. For a P25 system, only the inhibit function is available. Details of the functions are: (a). Invert. When the ‘Invert’ option is selected, the phase of the audio input signal will be inverted (phase reversal).
SGD-SB2025NT-TUM, Part 2 5.2.1.7 Offset The ‘Offset’ facility (see Figure 35 below) is provided in order to adjust the relative delay of the audio output if there is a need to artificially compensate for signal overlap areas that are not equidistant from sites. The range of delay available is from 0 µs to 255 µs and the required value is entered directly. An entry that exceeds the maximum will automatically be changed to 255 µs when applied.
SGD-SB2025NT-TUM, Part 2 Figure 38. NI Engineering – Signalling page. 5.2.2.1 Signalling In The signalling input may take the form of a variable voltage or tone. The NI will automatically determine the meaning of this input according to the mode of operation, i.e. Central or Station, although setting to ‘Voltage’ has no meaning for an NI operating in Central mode. The type of signalling required is selected from the drop-down list as shown in Figure 39. Figure 39. Signalling In – Menu Options.
SGD-SB2025NT-TUM, Part 2 1. Apply a signal level to the Rx of minimum RSSI, typically a mute threshold level. 2. Subtract 10 (see note) from the ‘Signalling Status’ measured value of voltage and enter this into the minimum Boundary box. Note. The subtract figure above is a suggested value to help ensure that the NI does not cut off low level signals when the receiver squelch may still be open (squelch hysteresis). 3. Apply a signal of maximum RSSI. 4.
SGD-SB2025NT-TUM, Part 2 Figure 41. Signalling Tone Output. The frequency range is 2.5 kHz to 3.5 kHz and, consequently, values entered outside this range will be changed to the closest limit when the ‘Apply’ button is selected. The tone level setting is in 2 dB steps covering the range of −10 dB to −28 dB relative to the peak system audio level, i.e. it is not an absolute level. The current level setting is shown at the foot of the slider.
SGD-SB2025NT-TUM, Part 2 Figure 42. Isolated Input Options. Each input is assigned to either a ‘Monitor’ mode, which provides a visual indication of the status of an input, or an ‘Auto’ mode, which pre-defines the duty of each input as shown overleaf in Table 1. The ‘(Inv)’ option of each setting inverts the “ON” state of the input; i.e.
SGD-SB2025NT-TUM, Part 2 Note. For FW Config builds other than the standard 0x7FFF, the Auto modes may produce a different operation to that shown in Table 1. See Section 15 – Firmware Extensions for more information. 5.2.2.5 Isolated Outputs Control of the isolated outputs (relays) and their current state is presented on the ‘Status’ page (this is the default view) and configured on the ‘Mode’ page. The Isolated Outputs ‘Status’ page and ‘Mode’ page are shown below in Figure 43. Figure 43.
SGD-SB2025NT-TUM, Part 2 More than one item may be changed at a time but the action must be completed by clicking ‘Apply’. At this point any new setting or text will turn Blue until full confirmation is received from the opposing end of the system. For text labels this will take several minutes as text is given lowest priority in the supervisory process. Table 2. Isolated O/P Functions in ‘Auto’ mode.
SGD-SB2025NT-TUM, Part 2 5.2.3.1 Name This is a user defined text label to aid identification of the NI. The name will be displayed in some of the TM ET windows to assist the user by confirming that the NI being viewed or altered is the correct one. To enter or change the text select the ‘Eng’ button (IN), click in the ‘Name’ text box and amend the text as required (the limit is 19 characters). As for all settings, a change must be completed by using ‘Apply’.
SGD-SB2025NT-TUM, Part 2 Figure 46. Test Tone Facility. 5.2.3.3.3 Route The test tone may be sent to either the ‘External’ (the analogue output), ‘Network’ towards the TM or both by setting that route to “ON”. It is the selection of the ‘Route’ that activates the test tone. Selecting the ‘Network’ route at a Station NI will need to be accompanied by a valid RSSI level (and mute open condition if so configured) for the test tone to pass through the TM and be output from the Central NI.
SGD-SB2025NT-TUM, Part 2 Figure 47. CTCSS Tone level. 5.2.4 Environment The ‘Environment I/O’ interface is an independent sub-module within the Solar 2 unit. It is accessible from and available to any of the main modules that are fitted to the unit. Consequently, any action or setting applied through one module is visible to and open to change through another module.
SGD-SB2025NT-TUM, Part 2 5.2.4.1 Status The state of the inputs and control of the outputs is presented on the ‘Status’ page for each group, which is the default view. To change the state of an output, select the ‘Eng’ button (IN), select the button of the required output(s) then select ‘Apply’ to invoke the change. The inner square of the button will turn Blue until the change is confirmed whereupon it will turn Grey again.
SGD-SB2025NT-TUM, Part 2 5.3 TM ENGINEERING (TM ET ONLY) ‘TM Engineering’ is accessed by clicking on the ‘Eng’ button on the TM Status panel. The settings accessed in the following pages are stored in the TM, some being sent to the NI for configuration purposes as part of the Solar supervisory system, others are sent for information purposes only. The ‘TM Engineering’ window also has an ‘Eng’ button that must be selected (IN) before a change can be made, whereupon the ‘Apply’ button will become active.
SGD-SB2025NT-TUM, Part 2 Figure 51. TM Engineering – Sync Timing (Central NIs). There are two ‘Sync Timing’ pages; one for the Station NI and one for the Central NI, each being selected by the corresponding tabs as seen in Figures 50 and 51 above. If the number of the NI in use exceeds the capacity of the display area, the slider to the right of each table allows the display area to be moved up and down to view every report.
SGD-SB2025NT-TUM, Part 2 5.3.1.2 Initial Values The principle is to start with nominal values and assume that these settings will require adjustment to values better suited to the IP network. This is especially true if the network has a means of alternate routing or fallback as the configuration offering ‘worst case’ values must be considered. Note. These buffer parameter values are global and apply to all channels on a multi-channel system.
SGD-SB2025NT-TUM, Part 2 5.3.2.1 Name To enter or change the ‘Name’ text, select the ‘Eng’ button, click in the ‘Name’ text box and enter or amend the text as required (the limit is 20 characters). As for all settings, a change must be completed by using ‘Apply’, which will take immediate effect as the information remains with the TM; i.e. it is not transmitted through the Solar supervisory system. 5.3.2.2 GPS Module The GPS/timing interface is an independent sub-module within the Solar 2 unit.
SGD-SB2025NT-TUM, Part 2 5.4 CHANNEL SETUP The ‘Channel Setup’ page for an Analogue system, shown below in Figure 54, is accessed via the ‘Setup’ button on the Channel Status Panel of the TM ET main window as shown in Section 3.4.2 – Channel Status Panel. Figure 54. Channel Setup page (Analogue).
SGD-SB2025NT-TUM, Part 2 5.4.2.3 Site Deselection Timer (Minutes) If an in-service base station Rx squelch is open for longer than this value, that station will be removed from the Voter list until that squelch is closed continuously for a short time (typically 10 seconds). If invoked, the Station panel will still indicate a received RSSI level but not a voted indication. 5.4.2.
SGD-SB2025NT-TUM, Part 2 The significant difference is that the page now contains ‘Main’ and ‘P25’ tabs, with the P25 features/parameters accessed via the P25 tab. The Main tab simply contains all the parameters for an Analogue system, which are detailed in Section 5.4 above. Figure 55. Channel Setup page (P25). The ‘Eng’ button must be selected to enable changes to be made and the ‘Apply’ must be selected to complete the changes. 5.5.1 Audio Mode The channel’s Audio Mode is set here.
SGD-SB2025NT-TUM, Part 2 6 SOLAR CHANNELS (RELATIONS) 6.1 MULTI-CHANNEL OVERVIEW The ‘Facility Key’ controlled Multi-channel option of the TM allows a collection of Station NI (sites) to be grouped together and operate as an independent sub-system of the parent Solar network. These groupings will be referred to as a “Solar Channel” and, although it is anticipated that all base stations or repeaters on a Solar Channel would be operating on the same radio frequency, it is not mandatory.
SGD-SB2025NT-TUM, Part 2 Figure 57. Relations Page. 6.2.2 Moving a Station to a Different Channel The following procedure is an example of how to move Station NI #1 from Channel #1 to Channel #2. The process is also shown in Figure 58 below. 1. Move the mouse pointer over Station NI#1 square, click and hold the left mouse button. 2. A square with a Green highlight and the number 1 in it will appear under the pointer. Drag this to the Channel #2 square, which will also gain a Green highlight. 3.
SGD-SB2025NT-TUM, Part 2 6.2.3 Moving a Central NI to a Different Channel The following procedure is an example of moving the Central NI #1 from Channel #1 to Channel #2. The process is very much the same as moving a Station NI and is shown below in Figure 59. 1. Move the mouse pointer over Central NI #1, click and hold the left mouse button. 2. A square with a Green highlight and the number 1 in it will appear under the pointer.
SGD-SB2025NT-TUM, Part 2 Figure 60. Examples of disabled NI. 6.3 LIST The function of ‘List’ is to present all the NI and Channels that are on the system in a single window for ease of identification. ‘List’ may be activated directly from the TM Status panel or via the ‘Relations’ window. Figure 61. Route to List facility. There are three lists in the window; one for Stations, one for Channels and one for Centrals. Each list is on its own page and accessed with the corresponding tab.

SGD-SB2025NT-TUM, Part 2 7 SOLAR (SYNC) TIMING 7.1 GENERAL The purpose of this section is to give the user an understanding of the way in which Solar operates in the context of packet timing and buffering, which is core to the task of delivering consistent and reliable audio over an IP network. There is more information on the specific subject of IP network changes and the effects on Solar operation in Section 11 – Troubleshooting & Maintenance. 7.1.
SGD-SB2025NT-TUM, Part 2 The data flow in a Solar network may be divided into four discrete parts: • Central NI to TM. • TM to Station NI. • Station NI to TM. • TM to Central NI. ‘Sync Timing’ which is part of the TM Engineering as shown in Figures 50 and 51 and described briefly in Section 5.3.1 – Sync Timing, has been arranged to reflect this separation of data flow. One page is concerned with the data flow between Central NI and TM and the other page with the data flow between TM and Station NI.
SGD-SB2025NT-TUM, Part 2 packet buffering, therefore maintaining approximate synchronisation. This fallback mode of timing is indicated by the text ‘NI’ where the ‘SV’ number is shown alongside the 1PPS status indication (now showing Red failed) on the TM status panel. 7.5 TIMING DIAGRAMS If the user wishes to gain a deeper understanding of the Solar timing process and the selection of the correct timing values, some timing diagrams have been produced.
SGD-SB2025NT-TUM, Part 2 8 TM DUPLICATION 8.1 DUPLICATION OVERVIEW The TM lies at the heart of a Solar network and loss of the TM whether due to a unit fault or network failure will have a severe impact upon the operational capability of the system. To mitigate the risk there is a “Facility Key” enabled option to have a second TM acting as a hot standby unit.
SGD-SB2025NT-TUM, Part 2 For example, if the Secondary TM has taken over the duties of the Primary TM in position two in the table, then loss of the Primary TM in position three will not result in any change in the function of the Secondary TM and the Solar channel(s) operated by Primary TM number three will be unavailable.
SGD-SB2025NT-TUM, Part 2 Figure 63. Setting for Duplicated (Primary). Note. If an IP address is entered that is the same as one already actively in use anywhere on the TM this will be cleared back to 0.0.0.0 when ‘Apply’ is clicked. The ‘Duplication Status’ text will now change to reflect the duplication setting and the colour of the indicator will show the status – see Section 8.2.4 below. 8.2.
SGD-SB2025NT-TUM, Part 2 2.5. Repeat Paras 2.3 and 2.4 for any further Primary TMs but ticking ‘IP Address’ box 2, 3 etc in order of their priority. 2.6. Select the ‘Apply’ and then the ‘Close’ buttons. Note. The IP address table also reflects the priority order in which the Secondary TM will take over from the Primary TM (highest priority is position 1, lowest priority is position 5).
SGD-SB2025NT-TUM, Part 2 9 DIAGNOSTICS AND OTHER INFORMATION 9.1 GPS If a GPS Rx is used to provide the 1PPS timing signal, it is likely that NMEA data will also be supplied. Information is taken from the NMEA data stream about the GPS Rx and displayed on the satellite signal report page. The ‘GPS’ button on the NI ET and the TM ET provides access to this page, which is designed to assist in the installation and any subsequent diagnostics of the GPS Rx.
SGD-SB2025NT-TUM, Part 2 Figure 68. Facility Key information. There are three aspects of information displayed about the Key: (a). ‘Serial #’. This is the unique number for the ‘Facility Key’ and ties it to the original supply. (b). ‘ID’. This is a short text string that outlines the facilities enabled by the Key. (c). ‘Status’. This indicates the status of the ‘Facility Key’ and will show Green when working correctly or turn Red under a fault condition. This will be accompanied by the text: (i).

SGD-SB2025NT-TUM, Part 2 10 RECEIVER VOTING 10.1 VOTING OVERVIEW The process of selecting the best signal from a collection of signals that are being returned from several Station NIs at remote radio sites is commonly referred to as “Voting”. This terminology will be used throughout this section. The voting process takes place in the TM unit at a digital level. In order that the TM can make a selection of the best incoming signal, information needs to be available on which the voting process can operate.
SGD-SB2025NT-TUM, Part 2 As this process is undertaken for every packet, the voting response time is 20 ms. Since the IP data packet contains both the RSSI information, the digitised audio and simultaneously conveys the fact that a signal is present, no audio will be lost at the start of an incoming signal due to the delay whilst the voter makes a signal assessment.
SGD-SB2025NT-TUM, Part 2 10.6 SQUELCH INPUT (COR) This is an optional input condition, since the RSSI input itself can be used to determine that the receiver is active once the input signal has reached the minimum boundary value. However, use of this input is strongly recommended to prevent false voting states if an RSSI voltage is used.
SGD-SB2025NT-TUM, Part 2 11 ET TROUBLESHOOTING AND MAINTENANCE 11.1 NETWORK LATENCY AND FAULTS The crucial parameters in the successful operation of Solar are the buffer times, which are set in the ‘Sync Timing’ page of the TM ET (see Section 7 – Solar (Sync) Timing for details). Making the buffers unnecessarily large will undoubtedly mean the Solar network will function but will introduce noticeable end-to-end audio delay especially for T/T operation.
SGD-SB2025NT-TUM, Part 2 11.1.3.1 Delay from NI to each TM The Solar network settings are held in the Primary TM and passed, in their entirety, to the Secondary TM, i.e. there is no provision to “customise” the Secondary TM in any way. Depending upon the network “distance” between the two TMs, it is quite reasonable to expect that some NIs will be ‘closer’ to the Primary than the Secondary and vice-versa.
SGD-SB2025NT-TUM, Part 2 Note. The ET cannot be used at the same time as the Loader software as they use the same com port on the equipment. Run the Loader application and “Connect” to the equipment in exactly the same way as for the ET. Follow the help guidelines for using the ET in Section 1.3. The current Firmware version will be reported once the connection is established. Figure 70. Loader Application.
SGD-SB2025NT-TUM, Part 2 If circumstances should somehow arise that results in the firmware file being corrupted, although the TM will not operate normally, it will run a special fall back program to allow the ‘Loader’ to be connected so that replacement firmware can be loaded. 11.2.4 Network Interface The NI will suspend normal operation during an upgrade. There are two Firmware programmes in the NI: (a). PIC Firmware.
SGD-SB2025NT-TUM, Part 2 12 ALARMS 12.1 ALARMS OVERVIEW The alarms facility of Solar is a useful feature especially for the smaller systems. It is designed to alert the user by means of an alerter device connected to a Central NI to a situation designated as requiring attention. Configuration of the alarms facility and any subsequent analysis into the nature of an alarm requires use the TM ET and, therefore, is not recommended for use by nonengineering staff.
SGD-SB2025NT-TUM, Part 2 12.3.1 Environment Inputs Each of the environment inputs may be selected to generate an alarm whenever that input is taken to an active state. As each on the sixteen connection points may be defined as an input or an output, only those defined as inputs are available to assign to an alarm; those defined as outputs do not support the alarm facility as shown by the button being unavailable.
SGD-SB2025NT-TUM, Part 2 Figure 74. Setting Misc Alarms for a NI. 12.3.4 TM Misc Alarms As an example, Figure 75 below shows that ‘Duplication’ and ‘PPS’ have been assigned to alarm status. Figure 75. Alarms Setup for a TM. 12.4 ALARM INDICATIONS 12.4.1 Alarm Active The presence of an alarm condition will be indicated by one or more flashing Red borders on the area(s) of the TM ET main window to indicate the source of the alarm(s).
SGD-SB2025NT-TUM, Part 2 Figure 76. Examples of Alarm Indications. 12.4.2 Alarm Acknowledge As an alarm indication will continue to be displayed even if the original event is no longer active, the alarm may be acknowledged so that the external alarm output, ‘Isolated Output #2’ on the Central NI, is deactivated. This also serves as a means of recognising if a subsequent alarm condition occurs before the first has been cleared.
SGD-SB2025NT-TUM, Part 2 Figure 77. PPS Alarm on the TM. The alarm example in Figure 78 below shows that alarms are present on the NI ‘Signalling’ and ‘Environment’ pages. The ‘Signalling’ alarm is due to ‘Isolated Input #3’ and acknowledging that changes the flashing border on the ‘Signalling’ tab and the input indicator to flashing Yellow whereupon the ‘Ack Alarms’ button becomes disabled. The alarm on the ‘Environment’ page must be acknowledged separately as shown overleaf in Figure 79. Figure 78.
SGD-SB2025NT-TUM, Part 2 Figure 79. Alarm on the NI Environment page. 12.5 TM DUPLICATION ALARMS 12.5.1 Alarms on a Secondary TM Just as for the other parameters in the Secondary TM, the definition of alarm events will be taken from the Primary TM; they cannot be different to the Primary TM or defined at the Secondary TM. However, alarm events must be acknowledged at each TM independently.
SGD-SB2025NT-TUM, Part 2 12.5.3 Secondary TM Alarm Acknowledged On acknowledging the Secondary TM alarm, the Secondary TM will resume communications with the Primary TM resulting in the acknowledged ‘Duplication’ alarm on the Primary TM ceasing. From that point on, it will not be automatically apparent, that the original alarm on the Secondary TM has cleared.
SGD-SB2025NT-TUM, Part 2 13 TM LOGGING 13.1 OVERVIEW This section describes the TM Logging facility that is an inherent feature of the TM and independent of all other options. Information is automatically gathered by the TM; the only setup required is that of setting system time. The data is stored in four log files, one covering each event subject. These are generated on a daily basis and are retained for 28 days.
SGD-SB2025NT-TUM, Part 2 The majority of entries in the system log are likely to be due to automatic functions although an event might be due to manual action elsewhere on the system. 13.2.3 Voter Log When a voter change occurs such as happens at the start of an incoming call or a change in voted site selection or at the end of a call, an entry is generated in the voter log. The information included with each entry is the RSSI signal level for every site within the channel.
SGD-SB2025NT-TUM, Part 2 Figure 81. The TM Logging window. 13.4 TM SYSTEM TIME TM system time is taken from the TM real-time clock, which will initially need to be configured to operate in the correct time zone. This information is gathered from the PC hosting the ET application and the clock will remain aligned to GPS UTC time when this is available with the appropriate time zone offset. If GPS is not directly connected to the TM, the internal clock may need to be reset again in the future.
SGD-SB2025NT-TUM, Part 2 13.5 LOG SELECTION Selection of the date of the log to be transferred to the ET is made by clicking on the date required on the calendar, which will gain the blue highlight; the default selection being the current date. There is no need to re-select the date if the correct date is already highlighted. The log event subject is selected from the pull-down list visible above the calendar. Figure 82. Selecting an Alarm Log.
SGD-SB2025NT-TUM, Part 2 Figure 83. Transferring a Log File to the ET. 13.6.1 Saving the Log When the log transfer process is complete, the ‘Save’ button will become active and remain active while the file is present in the ‘Log Display’ area. When the ‘Save’ button is selected, the ‘Save Log’ file page will open allowing the selection of folder and naming of the log file.
SGD-SB2025NT-TUM, Part 2 (b). ‘Channel’. The channel number encompassing the event is displayed when appropriate. On single channel versions this will only be “Chn 01”. (c). ‘Equipment’. The equipment or hardware unit that experienced the event. Typical data is “TM”, “Cen 01” and “Stn 02” etc. (d). ‘Type’. The area of the equipment in which the event occurred. Typical data is “File”, “Key” and “NI”, etc. (e). ‘Event’. The details of the event itself.
SGD-SB2025NT-TUM, Part 2 Figure 86. Applying a Display Filter. Figure 87. Filtering the Log Display on ‘Channel’. Figure 88. Filtering the Log Display on ‘Type’. More than one column may be filtered at the same time. To remove a filter select ‘All’ from the drop-down list. A filter must be removed before selection of a different filter item can be made in order to show the full list of selectable items.
SGD-SB2025NT-TUM, Part 2 13.7 EVENTS ACROSS MULTIPLE LOGS There will be events that cause a log entry to occur in more than one event log. An example of such a situation is the loss of the PPS signal at a NI. This could be logged as an alarm (if so configured) but would also be logged as a system event as the TM would remove the entry for that NI from the timing table.
SGD-SB2025NT-TUM, Part 2 14 SNMP 14.1 OVERVIEW OF SNMP IN SOLAR This section details the setting up necessary to implement the SNMP facility and the functions that are available through it. However, it does not go into any detail of SNMP operation, as it is assumed the user will already have knowledge of and be familiar with SNMP. This feature is a ‘Facility Key’ enabled option which requires the Solar 2 ET and MIB file ‘DALMAN-SOLAR-MIB011.txt’ or higher.
SGD-SB2025NT-TUM, Part 2 Figure 89. SNMP Text Label/Data Entry. 14.2.2 Trap Destinations The IP addresses entered into any of these fields (to a maximum of six) will be the locations to which any trap event notification is sent. To enter or change an IP address, depress the ‘Eng’ button and position the mouse pointer on the entry to be changed or added and click the mouse button to activate the edit cursor (caret). Figure 90. SNMP Trap Address Entry.
SGD-SB2025NT-TUM, Part 2 14.3 DATA ORGANISATION The data and meaning of the information that can be monitored by the SNMP NMS is detailed in a MIB file. This file is provided by Simoco and contains all the necessary references, plain text translations and value limitations that are applicable to every item of data that is accessible with the NMS using SNMP. 14.3.1 Data Format A summary of the data is set out in the following tables and the meaning of each column headings is: (a). Data Item.

SGD-SB2025NT-TUM, Part 2 15 FIRMWARE EXTENSIONS 15.1 FIRMWARE EXTENSIONS – OVERVIEW The firmware installed in a NI is the same for all users. However, extension modules are supported in the firmware, which will be created to perform specific and dedicated functions. These extension modules will be activated according to the setting of the FW Config Byte, which is displayed on the ‘Facilities’ page of ‘NI Engineering’ (see Section 8.2.3 – Facilities).
SGD-SB2025NT-TM, Part 2 APPENDIX A SOLAR CONFIGURABLE SETTINGS The intention here is to list the user configurable settings of a Solar network in alphabetical order and to indicate which ET has access to which. The precursor to any change is likely to need selection of an engineering mode and the conclusion being that the change needs to be applied (see the relevant section in the handbook for full details).
